Abstract
AIM The primary aim of the European Society of Coloproctology (ESCP) Guideline Development Group (GDG) was to produce high-quality, evidence-based guidelines for the management of cryptoglandular anal fistula with input from a multidisciplinary group and using transparent, reproducible methodology. METHODS Previously published methodology in guideline development by the ESCP has been replicated in this project. The guideline development process followed the requirements of the AGREE-S tool kit. Six phases can be identified in the methodology. Phase one sets the scope of the guideline, which addresses the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula in adult patients presenting to secondary care. The target population for this guideline are healthcare practitioners in secondary care and patients interested in understanding the clinical evidence available for various surgical interventions for anal fistula. Phase two involved formulation of the GDG. The GDG consisted of 21 coloproctologists, three research fellows, a radiologist and a methodologist. Stakeholders were chosen for their clinical and academic involvement in the management of anal fistula as well as being representative of the geographical variation among the ESCP membership. Five patients were recruited from patient groups to review the draft guideline. These patients attended two virtual meetings to discuss the evidence and suggest amendments. In phase three, patient/population, intervention, comparison and outcomes questions were formulated by the GDG. The GDG ratified 250 questions and chose 45 for inclusion in the guideline. In phase four, critical and important outcomes were confirmed for inclusion. Important outcomes were pain and wound healing. Critical outcomes were fistula healing, fistula recurrence and incontinence. These outcomes formed part of the inclusion criteria for the literature search. In phase five, a literature search was performed of MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews by eight teams of the GDG. Data were extracted and submitted for review by the GDG in a draft guideline. The most recent systematic reviews were prioritized for inclusion. Studies published since the most recent systematic review were included in our analysis by conducting a new meta-analysis using Review manager. In phase six, recommendations were formulated, using grading of recommendations, assessment, development, and evaluations, in three virtual meetings of the GDG. RESULTS In seven sections covering the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula, there are 42 recommendations. CONCLUSION This is an up-to-date international guideline on the management of cryptoglandular anal fistula using methodology prescribed by the AGREE enterprise.

Abstract
Cryptoglandular anal fistulas are one of the most common colorectal diseases and occur with an incidence of about 20/100,000. Anal fistulas are defined as an inflammatory junction between the anal canal and the perianal skin. They develop from an abscess or chronic infection of the anorectum. Surgical treatment of the disease is the method of choice. Even when treating an acute abscess, its cause should be sought at the same time. If there is a connection to the anal canal without affecting relevant parts of the sphincter muscles, primary fistulotomy should be performed. If larger parts of the sphincter muscle are involved, the insertion of a seton drain is usually useful. There are essentially two recommendations for the elective treatment of cryptoglandular anal fistulas. Distal fistulas should be excised, with the proviso that as little sphincter muscle as possible is sacrificed. In the case of highly proximally located and complex fistulas, sphincter-preserving surgical techniques should be used. In this case, the method of choice is the mucosal or advancement flap. Alternatively, clips, fibrin injections, fistula plugs, fistula ligatures, or laser-based procedures are described in the literature. In the case of intermediate fistulas, a fistulectomy with primary sphincter reconstruction can be useful. Every operation is carried out as a compromise between definitive healing of the fistula and a potential risk to the patient's continence. It is often difficult to make a reliable prognosis about the continence function to be expected postoperatively. In addition to the fistula morphology, particular attention should be paid to whether previous proctological operations have already been performed, the gender of the patient, and whether there are pre-existing sphincter dysfunctions. Since the surgeon's expertise plays a decisive role in the success of the treatment, the procedure should be carried out in a specialist proctological centre, especially in the case of complex fistulas or in the case of a condition after previous operations. In addition to the classic procedures, such as fistulectomy or the plastic fistula closure, this article examines alternative methods and their areas of application.

Abstract
Anal fistulas are common anorectal conditions, and surgery is the primary treatment option. In the last 20 years of literature, there exist a large number of surgical procedures, especially for the treatment of complex anal fistulas, as they present more recurrences and continence problems than simple anal fistulas. To date, there are no guidelines for choosing the best technique. We conducted a recent literature review, mainly the last 20 years, based on the PubMed and Google Scholar medical databases, with the goal of identifying the surgical procedures with the highest success rates, lowest recurrence rates, and best safety profiles. Clinical trials, retrospective studies, review articles, comparative studies, recent systematic reviews, and meta-analyses for various surgical techniques, as well as the latest guidelines of the American Society of Colon and Rectal Surgeons, the Association of Coloproctology of Great Britain and Ireland, and the German S3 guidelines on simple and complex fistulas were reviewed. According to the literature, there is no recommendation for the optimal surgical technique. The etiology, complexity, and many other factors affect the outcome. In simple intersphincteric anal fistulas, fistulotomy is the procedure of choice. In simple low transsphincteric fistulas, the patient's selection is crucial in order to perform a safe fistulotomy or another sphincter-saving technique. The healing rate in simple anal fistulas is higher than 95% with low recurrence and without significant postoperative complications. In complex anal fistulas, only sphincter-saving techniques should be used; the optimal outcomes are obtained by the ligation of the intersphincteric fistulous tract (LIFT) and rectal advancement flaps. Those techniques assure high healing rates of 60-90%. The novel technique of the transanal opening of the intersphincteric space (TROPIS) is under evaluation. The novel sphincter-saving techniques of fistula laser closure (FiLac) and video-assisted anal fistula treatment (VAAFT) are safe, with reported healing rates ranging from 65% to 90%. Surgeons should be familiar with all sphincter-saving techniques in order to face the variability of the fistulas-in-ano. Currently, there is no universally superior technique that can treat all fistulas.

Colorectal Dis 2023; 25:289-297. [PMID: 36128714 DOI: 10.1111/codi.16344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 09/04/2022] [Accepted: 09/06/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND The most effective treatment for anal fistula is fistulotomy, but it involves a risk of anal incontinence. To reduce this morbidity, sphincter-sparing treatments have been developed, but their success in real life is often less than 50%. The aim is to determine the clinical healing rate 6 months after radiofrequency treatment. METHODS We planned to evaluate 50 patients from three French proctology centres. Treatment efficacy was evaluated at 6 and 12 months by means of clinical and magnetic resonance imaging examination. We evaluated morbidity and healing prognostic factors. RESULTS Fifty patients with a mean age of 51 years (22-82) were included. Eleven patients had a low trans-sphincteric fistula (LTS), 21 patients had a high trans-sphincteric fistula (HTS), eight had a complex fistula and nine had Crohn's disease fistula. After 6 months, 17 patients (34.7%) had a clinically healed fistula, including five (45.5%) with LTS fistula, seven (33.3%) with HTS fistula, one (12.5%) with complex fistula, four (44.4%) with Crohn's disease, with no significant difference between these fistula types (p: 0.142). At 12 months, the healing rate was identical. MRI in 15 out of 17 clinically healed patients showed a deep remission of 73.3% at 12 months. Energy power was associated with the success of the treatment. There was an 8.2% incidence of post-surgical complications with 4.1% being abscesses (one required surgical management). Postoperative pain was minor. No new cases or deterioration of continence have been shown. CONCLUSION Radiofrequency is effective in 34.7% of the cases as an anal fistula treatment in this first prospective study, with low morbidity and no effect on continence. Clinical healing was deep (MRI) in three-quarters at 1 year. The increase in energy power during the procedure seems to be a key point to be analysed to optimise results.

Abstract
INTRODUCTION Anal fistula is the natural evolution of perianal abscess and one of the most common perianal diseases for adults. For complex fistula, it is still very challenging for anorectal surgeons to manage. With the introduction of laser technique in surgery, it is becoming more and more widely used for the treatment of cryptoglandular anal fistula. During the past decade, numerous studies have reported the clinical effectiveness and postoperative outcomes of different forms of laser treatment for anal fistula. However, as these studies were varied in terms of baseline characteristics, the evidence for the true clinical effectiveness of laser treatment for anal fistula need further critical appraisal. Therefore, the purpose of this study is to evaluate the outcomes of surgical laser therapy for cryptoglandular anal fistula stratified by laser type and Parks' classification through a synthesis of quantitative and qualitative evidence. METHODS AND ANALYSIS This study will be carried out with adherence to the Cochrane Handbook. We will search PubMed, Cochrane Library, and Embase until June, 2022 to identify all relevant interventional and observational studies examining the effects of laser therapy on the clinical outcomes for cryptoglandular anal fistula. Data extraction from eligible studies will be performed independently by two unblinded authors using standardized extraction forms. Risk of bias assessment for each study will be conducted using Cochrane tool for randomized controlled trials (RCTs) and the Newcastle-Ottawa scale (NOS) tool for observational studies. The DerSimonian-Laird random-effects model will be used to calculate the pooled estimates. Heterogeneity will be examined by subgroup analysis stratified by laser type and Parks' classification and other study characteristics. Potential publication bias will be assessed by funnel plot symmetrical and Egger's regression tests. CONCLUSIONS The synthesis of quantitative and qualitative evidence of this systemic review will yield updated and comprehensive evidence of laser treatment on specific outcomes, which can provide anorectal surgeons with high level evidence-based recommendations to improve patient care and clinical outcomes.

Abstract
Abstract
Objective Despite all the technological advances, successful management of complex fistula-in-ano is still a challenge due to recurrence and incontinence. The present study evaluates the outcomes of a novel technique, Interception of Fistula Track with Application of Ksharasutra (IFTAK) in terms of success rate and degree of incontinence.
Methods In the present prospective study, 300 patients with complex fistula-in-ano were treated by the IFTAK technique, whose surgical steps include: incision at the anterior or posterior midline perianal area, identification and interception of the fistulous track at the level of the external sphincter, rerouting the track (and extensions) at the site of interception, and application of a ksharasutra (medicated seton) in the proximal track (from the site of interception to the internal opening) that is laid open gradually, with the resulting wound healing with minimum scarring. The distal track is allowed to heal spontaneously.
Results There were 227 trans-sphincteric and 73 intersphincteric varieties of fistula with supralevator extension in 23 cases, of which 130 were recurrent fistulas, 29 had horseshoe track, while 25 had blind fistula with no cutaneous opening. The mean duration of the ksharasutra application was 8.11 ± 3.86 weeks with an overall success rate of 93.33% at the 1-year follow-up. A total of 3.67% of the cases reported with a mild impairment of continence on the Wexner incontinence scoring system. Pre- and postoperative anal manometry evaluation showed minimal reduction in median basal and squeeze pressures.
Conclusion The IFTAK technique is a minimally invasive, daycare surgical procedure for the management of complex fistula-in-ano with low recurrence and minimal sphincter damage.

Abstract
BACKGROUND Most patients with perianal fistulizing Crohn's disease (pfCD) present with complex types of perianal fistulas and need repetitive repair operations, resulting in a high risk of sphincter injury. Fistula-tract Laser Closure (FiLaC™) is a novel sphincter-saving technique that obliterates the fistula tract with a photothermal effect. The aim of the present systematic review and meta-analysis was to evaluate the efficacy and safety of FiLaC in pfCD. METHODS This study was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Electronic databases, including PubMed, Embase, Cochrane Library and Wanfang Data were searched for published articles from January 2000 to June 2021. The clinicaltrials.gov website was searched for completed or ongoing trials on pfCD and FiLaC™. The references of each article were also searched for eligible data. The main outcome was the primary healing rate of the FiLaC™ procedure. Additionally, fecal incontinence was analyzed as the secondary outcome to evaluate the safety of FiLaC™. RESULTS Six studies met the eligibility criteria and were included in the final analysis. All studies were published within the past 6 years and came from European countries. There were 50 pfCD patients recruited, and 31 patients' fistulas were healed after FiLaC™. The pooled primary healing rate was 68% (95% CI 53.0-84.0%, I2 = 27%, p = 0.23). There was no major fecal incontinence after surgery. CONCLUSIONS These data suggest that FiLaC™ may be an effective and safe procedure for pfCD patients. However, the evidence is poor and there is a need for more high-quality prospective controlled studies with long-term follow-up before this minimally invasive technique is recommended for surgical treatment of pfCD.

Abstract
BACKGROUND Video-Assisted Anal Fistula Treatment (VAAFT) is a novel minimally invasive & sphincter-saving technique for treating complex fistula-in-ano involving endoscopic assessment & treatment of perianal fistula. This retrospective, non-randomized, observational study is the first Australian study of VAAFT. It is also the longest study of VAAFT to-date. METHODS From January 2014 to September 2019, 59 patients with a complex anal fistula were identified via MRI & underwent VAAFT. Fourteen patients had undergone previous definitive surgery for anal fistula. Specialized Karl Storz video equipment (fistuloscope) was used in the procedure. The rigid fistuloscope was used to directly visualize the fistula tract/s & internal opening. Closure of the internal opening was then performed. The fistula tract/s were then treated via fulguration. The external opening was kept patent & dressed. Patients were then followed up for a mean 59.5 months. RESULTS 67.9% (n = 38) of patients achieved primary healing (needing nil further intervention) at a median of 13 weeks. 12.5% (n = 7) experienced healing followed by recurrence while 19.6% (n = 11) experienced non-healing. Of the recurrence/non-healing groups, 11/18 underwent repeat VAAFT with healing occurring in 10/11 patients at a median of 7 weeks. The mean operating time was 41.1 min. There were no major complications & continence scores were not affected. Three patients were lost to follow up. CONCLUSION VAAFT is both effective & safe for the treatment of complex fistula-in-ano. Its minimally invasive nature means that in the instance of recurrence or persistence, VAAFT can be repeated with minimal morbidity & reasonable likelihood of success.

Abstract
Objective This study intends to analyze the difference in the efficacy of drainage skin-bridge sparing surgery combined fistulotomy (DSCF) and fistulotomy alone. Methods 125 patients with anal fistula were enrolled as study subjects and randomly divided into control group (CG) and observation group (OG) by double-blind lottery. The CG received drainage skin-bridge sparing surgery with fistulotomy and the OG received fistulotomy only. Results The VAS scores of the trauma in the OG were lower than those in the CG on 1st day of surgery and 7 days after surgery (P < 0.05). The length of hospital stay and time to wound healing were shorter in the OG than in the CG (P < 0.05). The incidence of postoperative bleeding in the OG was 9.52%, which was lower than 22.58% in the CG (P < 0.05). The rectal examination scores were lower in the OG than in the CG at 3 and 5 days postoperatively (P < 0.05). The Wexner scores of solid incontinence (0 to 4), liquid incontinence (0 to 4), gas incontinence (0 to 4), pad wearing (0 to 4), and lifestyle alteration (0 to 4) in the OG were lower than those of the CG at 5 days postoperatively (P < 0.05). Voiding function scores were lower in the OG than in the CG at 2 and 3 days postoperatively (P < 0.05). Conclusions The efficacy of drainage skin-bridge sparing surgery combined fistulotomy is better than that of fistulotomy alone, which can accelerate postoperative healing, enhance urinary function, reduce postoperative bleeding, and improve anal function.

Abstract
PURPOSE Treatment of ano-cutaneous fistulas remains a therapeutic challenge. Fistula Laser Closure (FiLaC™) is a relatively new technique for the treatment of ano-cutaneous fistulas. This study aimed to determine the success rate of fistula closure using FiLaC™. Secondary endpoints included adverse events and patient characteristics associated with treatment success. METHODS This was a retrospective cohort study of consecutive patients subjected to FiLaC™ at Digestive Disease Center, Bispebjerg University Hospital, Copenhagen, between March 2017 and July 2019. All patients had a one-track fistula not suitable for fistulotomy. All were treated with a draining seton for at least 8 weeks prior to laser closure. Fistulas were ablated with a 360-degree emitting 12-watt 1470 nm laser probe. The inner fistula opening was closed with absorbable suture. All patients were followed with clinical examination including MRI or EAUS 1 year after the procedure. RESULTS In total, 66 patients with 68 fistulas were included. Two patients had a high intersphincteric, 20 had low transsphincteric, 41 high transsphincteric and 5 had suprasphincteric fistulas. Fistula aetiology was cryptoglandular in 83.8%, whereas the rest were due to Crohn's disease. Thirty-one (45.6%) were subjected to a second FiLaC™ procedure. Follow-up was median 19 months (12-26 months). Ultimately, 30 of 68 (44.1%) of the fistulas healed. No cases of incontinence following FiLaC™ were observed, but a single patient developed an abscess. CONCLUSION Fistula closure with FiLaC™ had success rates comparable to that of other sphincter-sparing techniques. The technique seems safe with respect to adverse events and risk of incontinence.

Abstract
BACKGROUND Therapeutic options for complex anal fistula (CAF) are limited. Video-assisted anal fistula treatment (VAAFT) allows examination of these anatomically complex fistulae from within. The aim of the present study was to evaluate outcomes of VAAFT for a series of CAF. METHODS A retrospective study was conducted on consecutive patients at a single centre with complex anal cryptoglandular and Crohn's fistulae managed with VAAFT from June 2016 to June 2019. CAF was diagnosed as high intersphincteric/transsphincteric tract, multiple/secondary tracts, horseshoe or anovaginal fistulae. Patients were treated with 'therapeutic intent' if the internal opening was closed at the time of ablation and 'diagnostic/staged/palliative' VAAFT if there was no ablation/partial treatment/ablation-only, respectively. Symptom improvement was a reduction in reported pain, discharge, or pad use. RESULTS Eighty-four patients (73 cryptoglandular, 11 Crohn's, M:F 2.5:1, median age 43 [22-77] years), underwent 105 VAAFT procedures. Twenty patients had > 1 VAAFT. Median follow-up was 8 (1-46) months. 40 (48%) had multiple or secondary tracts; an additional 16 (19%) had horseshoe and 3 (4%) anovaginal fistulae. Of the 84 patients, 19 [16/73 (22%) cryptoglandular and 3/11 (27%) Crohn's fistulae] healed. 34 (40%) unhealed reported improved symptoms; 23 (27%) no improvement; and 6 (7%) were worse. Sixteen (19%) had CAF > 5 years of whom none healed, albeit 50% reported symptom improvement. Five patients (6%) developed faecal incontinence: 2 temporary, 1 to flatus only and 1 to liquid and 1 to solid, all managed conservatively. CONCLUSIONS VAAFT is a useful minimally invasive procedure for complex fistula with no other minimally invasive options. Complete healing is rare, and, although symptoms can be improved in a number of cases, there is a small risk of incontinence.

Abstract
Objective Horseshoe anal fistula is a common anorectal disease, and there is no standard procedure for its treatment. In this study, we performed a modified surgical procedure for the treatment of horseshoe anal fistula and investigated its efficacy and adverse effects. Methods We retrospectively analyzed the outcomes of video-assisted anal fistula treatment combined with an anal fistula plug (VAAFT-Plug) in 26 patients with a horseshoe anal fistula. The follow-up period ranged from 6 to 18 months. Preoperative and postoperative data were collected to analyze the cure rate, anal sphincter function, and incidence of complications. Results The surgeries were successfully performed in all patients, 23 of whom were cured (effective cure rate of 88.46%). Three patients developed recurrence and were cured after traditional surgery. No patients developed severe complications or postoperative anal incontinence. The VAAFT-Plug protocol was performed with a small incision in the fistula that subsequently promoted fistula healing and preserved sphincter function. Conclusion Although randomized controlled trials will be needed to fully validate these findings, our results suggest that VAAFT-Plug represents a promising treatment strategy for horseshoe anal fistulas. This technique preserves normal anal function and achieves satisfactory outcomes in most patients.

Abstract
AIM Fistula Laser Closure (FiLaC™) is a novel sphincter-preserving technique that is based on new technologies and shows promising results in repairing anal fistulas whilst maintaining external sphincter function. The aim of the present meta-analysis is to present the efficacy and the safety of FiLaC™ in the management of anal fistula disease. METHOD The present proportional meta-analysis was designed using the PRISMA and AMSTAR guidelines. We searched MEDLINE, Scopus, clinicaltrials.gov, Embase, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar databases from inception until November 2019. RESULTS Overall, eight studies were included that recruited 476 patients. The pooled success rate of the technique was 63% (95% CI 50%-75%). The pooled complication rate was 8% (95% CI 1%-18%). Sixty-six per cent of patients had a transsphincteric fistula and 60% had undergone a previous surgical intervention, mainly the insertion of a seton (54%). The majority had a cryptoglandular fistula. Operation time and follow-up period were described for each study. CONCLUSION FiLaC™ seems to be an efficient therapeutic option for perianal fistula disease with an adequate level of safety that preserves quality of life. Nevertheless, randomized trials need to be designed to compare FiLaC™ with other procedures for the management of anal fistulas such as ligation of intersphincteric fistula tract, anal advancement flaps, fibrin glue, collagen paste, autologous adipose tissue, fistula plug and video-assisted anal fistula treatment.

Abstract
One of the most challenging phenotypes of Crohn’s disease is perianal fistulizing disease (PFCD). It occurs in up to 50% of the patients who also have symptoms in other parts of the gastrointestinal tract, and in 5% of the cases it occurs as the first manifestation. It is associated with severe symptoms, such as pain, fecal incontinence, and a significant reduction in quality of life. The presence of perianal disease in conjunction with Crohn’s disease portends a significantly worse disease course. These patients require close monitoring to identify those at risk of worsening disease, suboptimal biological drug levels, and signs of developing neoplasm. The last 2 decades have seen significant advancements in the management of PFCD. More recently, newer biologics, cell-based therapies, and novel surgical techniques have been introduced in the hope of improved outcomes. However, in refractory cases, many patients face the decision of having a stoma made and/or a proctectomy performed. In this review, we describe modern surgical management and the most recent advances in the management of complex PFCD, which will likely impact clinical practice.

Abstract
BACKGROUND Sphincter-preserving operations have been increasingly used for treating anal fistula. However, their success rates remain modest in complex anal fistulas. OBJECTIVE This study aimed to report outcomes of video-assisted ligation of intersphincteric fistula tract (a procedure combining video-assisted anal fistula treatment and ligation of intersphincteric fistula tract) for treating complex anal fistulas and to compare its results with conventional ligation of intersphincteric fistula tract. DESIGN A review of prospectively collected data from October 2014 to December 2017 was performed. SETTINGS The study was conducted at a large tertiary hospital in Thailand. PATIENTS All patients with primary or recurrent complex anal fistulas undergoing video-assisted ligation of intersphincteric fistula tract were included. Patients with anal fistula related to malignancy, Crohn's disease, tuberculosis, or acute abscess were excluded. MAIN OUTCOME MEASURES Healing as defined by an absence of fistula or drainage from an external opening and complete epithelialization of the external opening were measured. RESULTS This study included 103 patients with a median age of 47 years. The primary healing rate was 84.5% at a median follow-up of 28 months (range, 15-38 mo). Primary healing rates of anterior high transsphincteric fistula, semi-horseshoe fistula, and horseshoe fistula were 88% (44 of 50 cases), 77% (30 of 39 cases), and 93% (13 of 14 cases). Median time to healing was 4 weeks (range, 4-8 wk). Accordingly, the overall failure rate was 15.5%. None reported worse fecal incontinence postoperatively. Video-assisted ligation of intersphincteric fistula tract had a higher rate of primary healing for complex anal fistula than ligation of intersphincteric fistula tract (84.5% vs 63.4%; p < 0.001). LIMITATIONS This study is limited by its small sample size. CONCLUSIONS The outcomes of video-assisted ligation of intersphincteric fistula tract for complex anal fistulas are quite good. This technique has the potential to become another viable option of sphincter-preserving operation for complex anal fistulas. See Video Abstract at http://links.lww.com/DCR/B373. LIGADURA ASISTIDA POR VIDEO DEL TRACTO DE LA FÍSTULA INTERESFINTÉRICA PARA LA FÍSTULA ANAL COMPLEJA: TÉCNICA Y RESULTADOS PRELIMINARIES: Las operaciones de preservación del esfínter se han utilizado cada vez más para tratar la fístula anal. Sin embargo, sus tasas de éxito siguen siendo modestas en las fístulas anales complejas.Este estudio tuvo como objetivo informar los resultados de la ligadura asistida por video del tracto de la fístula interesfintérica (un procedimiento que combina el tratamiento de la fístula anal asistida por video y la ligadura del tracto de la fístula interesfintérica) para el tratamiento de las fístulas anales complejas y comparar sus resultados con la ligadura convencional de la fístula interesfintérica tracto.Se realizó una revisión de los datos recolectados prospectivamente desde Octubre de 2014 hasta Diciembre de 2017.El estudio se realizó en un gran hospital terciario en Tailandia.Se incluyeron todos los pacientes con fístulas anales complejas primarias o recurrentes sometidas a ligadura asistida por video del tracto de la fístula interesfintérica. Se excluyeron los pacientes con fístula anal relacionada con malignidad, enfermedad de Crohn, tuberculosis o absceso agudo.Curación definida por la ausencia de fístula o drenaje de la abertura externa y la epitelización completa de la abertura externa.Este estudio incluyó 103 pacientes con una mediana de edad de 47 años. La tasa de curación primaria fue del 84,5% con una mediana de seguimiento de 28 meses (rango 15-38). La tasa de curación primaria de la fístula transesfintérica alta anterior, la fístula semi-herradura y la fístula de herradura fue del 88% (44 de 50 casos), 77% (30 de 39 casos) y 93% (13 de 14 casos), respectivamente. El tiempo mediano hasta la curación fue de 4 semanas (rango 4-8). En consecuencia, la tasa de fracaso general fue del 15,5%. Ninguno informó peor incontinencia fecal después de la operación. La ligadura asistida por video del tracto de la fístula interesfintérica tuvo una mayor tasa de curación primaria para la fístula anal compleja que la ligadura del tracto de la fístula interesfintérica (84.5% vs 63.4%; p <0.001).Este estudio está limitado por su pequeño tamaño de muestra.Los resultados de la ligadura asistida por video del tracto de la fístula interesfintérica para fístulas anales complejas son bastante buenos. Esta técnica tiene el potencial de convertirse en otra opción viable de operación de preservación del esfínter para fístulas anales complejas. Consulte Video Resumen en http://links.lww.com/DCR/B373.

Abstract
PURPOSE We determined the outcomes of patients undergoing video-assisted anal fistula treatment (VAAFT) for fistulain-ano at the Philippine General Hospital. METHODS Twenty consecutive adult patients who underwent the VAAFT procedure from 2016-2018 were included in this investigation. Information detailing baseline demographic and clinical data, fistula type and classification, and previous surgeries were retrieved from in-hospital and operative records. Operative time, identification of the internal opening, method of internal opening closure, and occurrence of immediate postoperative complications were determined. The status of the fistula was assessed at one month, 3 months, and 6 months postoperatively based on outpatient follow-up records. The primary outcomes were healing rate and recurrence rate. Secondary outcomes were 30-day morbidity, postoperative complications, and incontinence using the Wexner score. RESULTS Eighteen patients (90%) had a preoperative diagnosis of complex fistula, and 13 patients (65%) had undergone a previous fistula surgery. Primary healing rate was 55% at 1 month, 63.16% at 3 months, and 78.95% at 6 months postoperatively. Eighteen patients (94.74%) maintained continence (Wexner score = 0) at 6 months. CONCLUSION Our study results suggest that VAAFT is a safe, minimally invasive technique for treatment of anal fistula and can preserve anal sphincter function. The technique has an acceptable healing rate with minimal complications.

Abstract
Perianal sepsis is a common condition ranging from acute abscess to chronic anal fistula. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. Surgery is the main treatment and several procedures have been developed, but the risks of recurrence and of impairment of continence still seem to be an unresolved issue. This statement reviews the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

Abstract
Idiopathic cryptoglandular fistula-in-ano is a common pathological condition. Fistula-in-ano has been managed by a number of surgical techniques, and there is still no consensus regarding the management of this condition. Surgical techniques aim to treat and cure the fistula-in-ano with minimal risk of recurrence or complications, and to maintain patient continence. This article discusses the evidence available to inform the management of idiopathic cryptoglandular fistula-in-ano, and problems that surgeons face because of the lack of high-quality evidence.

Abstract
AIM Due to fear of incontinence, fistulotomy perhaps remains highly underutilized. The aim was to analyze the efficacy of fistulotomy in a large cohort, to assess the magnitude of underutilization of fistulotomy by current classifications and to identify the subgroup in whom the fistulotomy should be done. METHODS All consecutive operated patients of fistula-in-ano were included in the study retrospectively. The fistulas were classified as per existing classifications-Parks, St James University Hospital (SJUH) and Garg classification. Smaller grades of each classification (Parks I, SJUH I-II, Garg I-II) were expected to be simple fistulas and thus amenable to fistulotomy. Objective incontinence scores were done preoperatively and postoperatively. RESULTS 675 patients were operated over a 5.5 year period (median-27 months). 25 patients were excluded. Fistulotomy was done in 353/650 (54.3%) patients and sphincter-saving procedures (SSP) performed in 297/650 (45.7%) patients. After fistulotomy, 346/353 (98%) fistulas healed after the first operation. Seven patients with recurrent fistula were cured after a repeat fistulotomy surgery. Thus the overall healing rate was 353/353 (100%). There was no significant change in continence scores. The 353 fistulotomy patients were classified as per different classifications- Parks (I-225,II-112,III-16,IV-0), SJUH(I-138,II-87,III-47,IV-65,V-16) and Garg (I-188,II-165,III-0,IV-0,V-0). 123 (36.3%) patients who could undergo fistulotomy successful were erroneously classified as complex fistula by Parks and SJUH classifications. Garg classification accurately identified all 353/353 (100%) patients were amenable to fistulotomy. CONCLUSIONS Fistulotomy is a safe procedure with remarkably high success rate (100%) and is gold-standard in majority of patients (>50%). Parks and SJUH classifications are inaccurate in selecting patients for fistulotomy. Garg classification predicts amenability to fistulotomy with very high accuracy.
